Abstract: PURPOSE:To improve brightness and to resolve the problem of the heat resistance of a polarizing plate by splitting light into P- and S-polarizing waves, modulating at least either of the polarizing waves with an optical modulating system, and magnifying and projecting it on a screen. CONSTITUTION:The light emitting from a light source 1 is split into two polarizing waves of S- and P-polarizations whose polarizing surfaces are intersected orthogonally with each other by a polarizing beam splitter 13, the S-polarization in incident light is transmitted and the P-polarization is reflected. The S-polarizing wave is reflected by a total reflection mirror 15 and is made incident on a liquid crystal panel 17 as the S-polarizing wave. On the other hand, the P-polarizing wave emitting from the polarizing beam splitter 13 is totally reflected by a total reflection mirror 16, and made incident on a liquid crystal panel 18 as the P-polarizing wave. Thus, the first polarizing beam splitter 13 splits the light from the light source into two polarizing waves of P- and S-polarizations which are intersected orthogonally with each other in advance, and acts so that at least either of the polarizing waves is optically modulated with the optical modulating system, magnified, and projected on the screen. Thus, the trouble of the heat resistance of the polarizing plate is eliminated, and the brightness can be easily improved.

Abstract: PURPOSE:To enable to adapt to the rapid heating and cooling, also obtain the fluid heating device having high thermal efficiency by a method wherein a burning exhaust gas produced in a burning chamber is passed through gas-permeable solid body, then a radiation heat is made to be radiated from the solid body to the outer surface of a periphery wall of a fluid vessel. CONSTITUTION:A fluid to be heated is passed through the inside of a fluid vessel 1, a burning chamber 2 is faced to the outer surface 3 of the periphery wall of the fluid vessel 1 and enclosed with gas-permeable solid body 4. A burner 6 is provided to blow- off a flame into the burning chamber 2, a burning exhaust gas produced by the burner 6 is made to be discharged after passing through the air-permeable solid body 4. Therefore, a radiation heat is radiated from the gas-permeable solid body 4 to the outer surface 3 of the periphery wall, accordingly, a heat energy contained in the burning exhaust gas can be directly utilized for the heating of the fluid vessel 1. Thus, the heating device having a low energy loss and a high thermal efficiency can be obtained. In case of the installing of the heating device, an insulating wall is not necessary as a conventional type boiler. Due to the small thermal capacity of the burning chamber, the heating time can be reduced, also the rapid heating and cooling can be achieved.
